A 12 Claims.

This invention relates to the class of winding and reeling and has to do particularly with an improved method and means of winding rolls of paper, more particularly small or counter rolls from major stock rolls.

A principal object of the present invention is to provide a method and means for carrying out the same of winding small or counter rolls of paper from a parent roll continuously whereby after the paper web has been initially started upona winding shaft or reel, rolls may be continuously formed and separated one from the other without having to give further attention to the starting of the web on a winding reel.

Another object of the invention is to provide a method of the character stated together with means for carrying out the same, whereby winding reels are continuously alternately employed for the forming of small rolls of paper from a parent roll without requiring the operator of the machine to give further attention to the starting of the paper web after the initial roll has been started and whereby the severing of the web from each roll as the latter is completed and the securing of the end of the web to the body of the roll is automatically effected.

Still another object of the invention is to pro- I vide a means by which small rolls of paper may tate its quick removal from the finished roll and I to facilitate its replacement upon the winding the salient features of the invention as expressed h in the appended claims.

In the drawings:

Fig. 1 is a view in elevation of the mechanism employed in carrying out the present method.

Fig. 2 is a longitudinal sectional view of a winding core or reel, the central portion of which has been broken away.

Fig. 3 is a section on the line 3-3I of Fig. 2.

Fig. 4 is a detail sectional view showing means,

for securing the winding cores against rotation. Figs. 5, 6, 7, 8 and 9 illustrate progressive steps in the carrying out of the method of winding small rolls of paper from a large or parent roll according to the present invention.

Referring now more particularly to the drawings, there is shown in Fig. 1 an upright frame structure which includes vertical side members or posts l between the lower ends of which a cated by the numeral 5 in Fig. 5, or from a paper machine in such manner with respect to the paper web that a new roll of paper may be started thereon without requiring the operator of the machine to thread the paper web through the core orperform any other similar service in connection therewith.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming part of this specification, with the understanding, however, that the invention is not to be confined to any strict conformity with the showing of the drawings but may be changed or modified so long as such changes or modifications mark no material departure from machine, is trained. Rotatably supported above this steel roll d is a shaft 6 carrying cutter wheels 'l which coact with the steel roll e to cutl the paper web in strips of reduced width.

Beneath the steel roll' 4 there is Supported a power shaft 8 which is mounted at its ends in bearings 9 carried by the standards or posts l,

and this power shaft may be provided with any suitable means for facilitating the connection of a driving engine -therewith, such as the belt pulley l0. Supported upon the shaft 8 is a shiftable driving gear ll which has formed integrally therewith the peripherally grooved hub l2 in the groove of which a shifting fork I3 is engaged to facilitate sliding the gear ll on the shaft 8, the

'gear being coupled to the shaft against rotation independently thereof by a key i4.

The drive gear Il is mounted upon the shaft B adjacent one end thereof and betwen thisvides at each end of the rotary frame two oppositely directed radial arms.

Each end of each of the bars I5, I8 'is formed to provide a cradle I1 for an end of a core or reel lshaft I8 and the ends of these core shafts are maintained in position in such cradles by cross bolts or pins I9. y

Each of these core shafts on which the smaller rolls are wound comprises two end pieces or trunnions 20 and 2| which engage in the ends of the arms I and I6, and each of such trunnions has integraly connected ...with its inner end a socket member, the socket for the trunnion 28 being indicated bythe numeral 22 while that forlthe trunnion 2| is indicated by the numeral 23. The trunnion 2|exteris into the socket 23 and is screw-threaded as indicated at 24.

Extending transversely of the. socket 22 is` a cylindrical locking cam .25, the ends'of which are eccentrically rotatably supported in opposite sides of the socket, as illustrated in Fig. 3, through the medium of the longitudinally extending pins 26, one of which is of polygonal the rotating frame I1 against rotation upon the shaft 8. Suitable spring means may be employed for normally urging the latching pin 36 into engaging position with the bar I6, as indicated at 31 in Fig. 4, this spring here being shown enclosed in a housing 38 and having one end bearing against the end of the housing and its other end bearing against a collar 39 which is fixed to the pin 36. The outer end ofthe latching pin is engaged by a bell crank or other suitable means 40V by which the retraction of the pin is eifected.

The numeral 4I designates a brake roll which is supported from the shaft 8 between the bars I5-I6, by the arms 42 which are journaled on the shaft to swing freely and the brake roll 4I, therefore, is normally suspended beneath the shaft 3 and in parallel relation therewith.

form, as at 2.1, to facilitate connection of a wrench with the lock for turning the same.

Ihe sockets 22-23 are operatively joined-to gether by two spaced parallel bars 28 and 29. The bar 28 has one end permanently secured in the socket 22, as shown in Fig. 2, while its other end is removably engaged in the opposite socket 23, being provided upon its inner face with threads 3|)l whereby it may be threadably coupled with the threaded inner end of the trunnion 2l to be secured between such end and the wall of the socket 23 in the manner shown in Fig. j

2. The opposite end is permanently secured in the socket 22 and is provided with a transverse recess 3| into which the locking cam 25 turns.

The bar 29 is completely detachable from the sockets 22--23, one end of this" bar being insertible into the socket 22 and having a recess 32 formed transversely thereof for reception of the cam lock 25 while the other end is insertible into the end of the socket 23 between the unthreaded end portion of the trunnion 2| and the wall of` the bar 28 to provide the paper web receiving slot 34. Disengagement of the bar 29 from the sockets is effected by turning the socket 23 so as to unthread the extended or threaded end of the trunnion 2l from the bar 28, thereby removing the threaded end of this bar from the socket 23 or, in other words, moving the sockets apart. This will free thev adjacent end of the bar 29 and the other end of the bar may be freed by turning the cam lock 25 so that such other end can be easily drawn out of the socket 22.

l Each of the core bars I8 has the trunnion 20 thereof provided with a driven gear 35, these gears being in offset vertical planes but arranged sufficiently closely together to facilitate the selec- I tive connection with them .of the drive gear II. The post I carries alatching'pin 36 which is shiftable transversely of this post inwardly toward the adjacent bar I6 for engagementwith this bar so as to hold the same and consequently` Supported by and between the arms 43 which are pivotally attached to the posts I is a serrated cut-off knife supporting bar 44, the knife which is` carried by this bar being indicated by the numeral 45 and extending longitudinally of the bar as shown, with the cutting or toothed edge directed upwardly. A lever 46 is connected with one of the arms 4-3 and facilitates swinging the knife 45 upwardly from a position beneath the platform 2 to a position above the lowermost one of thetwo core shafts I8. These core shafts are normally maintainedby the latch pin 36 in vertically spaced relation. The bar 44 also carries a pasting rubber or dauber strip 41 which lies beneath and in Iparallel relation with the 'knife 45 and when the knife is in its lowered position, this pasting rubber contacts a paste transfer roller 48 which receives paste from any suitable source or in any suitable manner so as to transfer the paste to the end of a finished roll as such end is formed by the operation of the cutting knife 45.

In carrying out the paper winding method according to the present invention, the paper strip or web is brought over the steel roller 4 either from a large parent roll 5, as indicated in Fig. 5, or from a paper machinebeing passedbeneath the cutting knives 1 and downwardly to the uppermost one of the core shafts I8. The papery is illustrated in Fig. 5 where one o f the smaller rolls is shown upon the upper core shaft and indicated by the numeral 49.

While the top roll is being formed or is winding, and without stopping the winding operation,

' the trip latch 36 is retracted so as to release the bar I6 with the result that the entire frame I1 will be turned over or will be caused to make one half a turn through the action of the driving gear II against the gear 35 with which it is in mesh. Since the latch 36 will immediately move back into operative position, it will be seen that it will function to vprevent the arm I6 and the parts connected therewith from-making more than this half turn. 'I'his brings the bar 28 of thelower core shaft around into the position shown in Fig. 6 and transfers the previously uppermost core shaft I8 to the lower position from which the previously lower bar has been removed, carrying the paper web or strip downwardly across the face of the shaft 8 and bringing it toy bear against the brake roller 4I, -forcing the latter backward as shown in Fig. .6. The bar 29 is now placed in position to complete the upper core shaft, as shown in Fig. 7, and the paper web now passes through the -slot -34 which is-formed between these bars; being continued to be added to the roll 49,'as shown in this figure.

When the roll 49 is complete as shown in Fig. 8, the drive gear II is shifted or thrown over to disengage from the lowermost gear`35 and to engage with the uppermost gear v35 which is connected with the uppermost core shaft I8 whereupon this uppermost core shaft will begin to rotate to wind up' the paper web thereon from the source of supply and also from the underlying roll 49, the roller 4I meanwhile acting as a brake, bearing against the lower roll 49, as-shown in Fig. 8.

The lever 4B is now swung upwardly so-as to bring the serrated cutting knife 45 -up into the position shown in Fig. 8 where it will cut the web free turning thereabout independently of the driven shaft, means for selectively coupling the driven shaft with the cores for effecting their turning on the supporting means and through the driven shaft, and means releasably holding the core supporting means against turning on the shaft.

2. A winding mechanism of the character described, comprising a winding frame having two just above the shaft 8 and where the paste applying rubber or dauber strip 41 will simultane supporting the lower core shaft I8 and the roll 49 may then be withdrawn to allow the roll to drop 'out onto the platform 2, as shown in Fig. 9. During this procedure a new roll or series of rolls 50 is being built -up upon the upper core shaft, as shown n Fig. 9. After the paper roll 49 or a series of such rolls has been removed, the core shaft' is taken out by unthreadng or backing oi the socket member 23 from the bar 28, this procedure releasing the adjacent end of the bar 29. The locking eccentric 25 is then turned up into therecess 3I so as to release the other end of the bar 29, thus permitting this bar to be entirely withdrawn from the paper roll and also permitting the bar 28 to be drawn out from the center of the paper roll, leaving the roll without a central core. The socket 23 is then replaced upon the end of the bar 28 and this bar with the two sockets and end trunnions is then placed back into Aposition between the lower ends of the bars I5, I6. without the bar 29, thus preparing the frame I1 for a repetition of the procedure described in connection with to start the paper web on either of the core shafts for the winding of any of the rolls.

In order that the paper web may be kept tight, I a tension roll 5I may be employed in advance of the steel cutting roll d or between the same and the parent roll, as shown in the Figs. 5 to 9 inelusive.
